Toall whom ttymay concern: y

Be it known that I, ANANIASWSMLTH, of Niagara Falls, in the county `ofNiagara and State `of New York, have invented certain new i and usefulImprovements in the Apparatus Used for Condensing Steam in. Steam-Engines, and that the following description, taken in connection withthe;accompanying` drawings, hereinafter referred to, forms a full and"exact specication of the same, wherein I have set forth theA naturel andprinciples@ of my said improvements, by which my invention may bedistinguished from all others of a similar class, together with suchparts as I claim and `desire tohave secured to me by Letters Patent.

The figures of the accompanying plate of drawings represent myimprovements. l

Figure l is a general sectional view of my improved condenser. Fig. 2 isat section taken in the plane of the line A B, Fig. l. Fig. 3 is adetail section.

The evils resulting from the use `of impure water in steam boilersarewellknown, as are `also the many unsuccessful devicesatwater, such assurface condensers, which were supposed to have accomplished thedesiredresults, and to prove of great use in marine engines, as theypermitted theuse of fresh water for the `boilers by iemploying thefeed-water over and over again. `.Their imperfections in practice have`long been demonstrated and need not beherefenumerated. `4

The present invention accomplishes all the desirable results heretoforeaimed :at in condensing apparatus, such as supplying; the boiler withpure Water, and thereby preventing the formation of scales and thedeposit of impurities in the boiler-using thesame feed water over andover again-feeding the boiler with heated water and thereby making agreat saving in the consumptionof fuel-fkeeping the water in the boileralways at one uniform level so as to form a perfectwater-gage--preventing all back pressure of steam upon `the piston-andmany other advantages which will `readily be apparent to engineers andothers by inspection of the apparatus as hereinafter described andrepresented in the drawings.

In my new apparatus the exhaust steam is condensed in such a manner andby such a mechanical device, that a vacuum or a partial vacuumor spaceis formed between the For. l

A reserveWater tank may be used to supply the boiler, by means of a pump, Withwhat small quantity of Water may be lost by leaks, &c., in thevjoints.When a supply is `not Wanted from this tank a cock shuts off itscommunication With the pump.

Having thus fully described my said improvement in apparatus forcondensing steam, what I claim as new and useful and desire to havesecured to me by Letters Patent is Y l. The employment, inV connectionwith a steam-engine and its boiler, of a revolving bucket Wheel arrangedto receive the exhaust steam from the engine and made to rotate in areverse direction to ,its issues in a cylinder or vessel containingWater from which the boiler of the engine is fed;

the exhaust steam being condensed by direct impingement with and addingtoV said feed Water essentially as specified.

2. The combination', With the revolving bucket or Wheel constructed toreceive the exhaust steam from theY engine, and cylinder or vesselcontaining the condensing liquid or feedwater in Which the Wheelrotates'and by direct contact With which Water the exhaust steam'iscondensed in the manner described,-of a surface cooling apparatus,formed by providing said feed Water vessel with a jacket or tubes, ortheir equivalents, through Which a cooling liquid is made to pass orcirculate free from adinixture with the Water in the vessel thatdirectly-effects the condensation of the steam substantially asspecified. f l
